SPECIFICATION forming part of Letters Patent No. 597,458, dated January 18, 1898.

Application filed November 12, 1896 Serial No. 611,831. (No model.)

To all whom t may concern:

Be it known that I, EZRA G. CLYMANS,a citizen of the United States, residing at Waynesborough, in the county of Franklin and State of Pennsylvania., have invented certain new and useful Improvements in Threshing-Machines 5 and l do hereby declare the following to be a full, clear, and exact description of the invention, such will enable others skilled lo in the art to which it appertains to make and use the same.

This invention relates to threshingmachines; and it consists in the novel construction and combination of the parts hereinafter r 5 fully described and claimed.

ln the drawings, Figure lis a longitudinal section through the rear portion of a threshing-machine constructed according to this invention. Fig. 2 is a detail plan view of a porzo tion of the straw-shaker. Fig. 3 is a detail plan view of a portion of the cleaning devices. Fig. 4C is a detail longitudinal section through the tailings-shoe, drawn to a larger scale, Fig. 5 is a detail front and plan view of one of the notched quadrants. Fig. 6 is a detail front and side View of one of the levers engaging with the said quadrants.

A is a portion of the casing of the machine. The grain is threshed out at the front end of 3o the machine by a cylinder and concave of approved construction. A is a guard-board at about the middle of the machine. Rakes oJ deliver the straw over the top of the guardboard, and ct is a grain bottom or pan which extends under the cylinder and delivers the grain and chaff under the guard-board. All these parts are of any approved construction, but th ey are preferably constructed as shown in a separate application, tiled February 1,7,

4o 1896, Serial No. 579,546.

B is a crank-shaft journaled at the rear of lthe guard-board A and provided with cranks h, arranged at opposite sides of its center so as to balance each other as much as possible.

B are teeth which project horizontally from the guard-board over the crank-shaft and preventthe straw f rom falling onto thecranks and becoming wrapped around the crankshaft. A splashcurtain h', of flexible maten 5o rial, such as canvas, depends from the guardboard behind the rear end of the grain-bottoni and, together with the guard-board, prevents grain from flying rearwardly through the machine. The grain-bottom is vibrated by means of similar eccentrics C on the ends of the crank-shaft B, and eccentric-rods C', driven by the said eccentrics and connected to the links c, which pivotally support the rear end of the grain-bottom. The eccentric rods and links are arranged outside the cas- 6o ing of the machine, and c' is a rod which is secured to the grain-bottom. This rod c' passes through slots in the casin g and has its ends carried by the links c.

D is a rearwardly and downwardly inclined 6 5 deector supported on ledges 7L in the upper part of the casing over the crank-shaft B. This detlector is preferably provided with a hinged extension D' at its lower end. This extensionv is normally supported by its hinges 7o d in the same plane with the deiiector and it is free to move upward. The dei-lector is preferably formed of wood faced with sheet metal, and its upper end is pivoted to the casing by the rod d.

E is a guardblock secured to the top of the casing to prevent the straw from sticking in the narrow space between the top of the casn ing and the deflector.

E is a stationary return-bottom or gather- 8o board supported in an upwardly and rear- Wardly inclined position in the upper part of the casing. Grate-bars F are supported above the return-bottom E. The front ends of the bars F are carried by the guard-board A', 85 and their rear ends are secured to the crosspiece 'e' at the rear end of the return-bottom. The sides of the grate-bars are provided with ratchet-shaped teeth f, and their rear end portions are provided with bridge-pieces f', 9o arranged vout of line with the grate -bars These bridge-pieces clear the cranks Z2 and are secured to the guard-board. The rear portions of the bridge-pieces extend downward, so that the lowest portions of the gratebars are supported below the tops of the cranks when in their highest positions.

Gr are rakes provided with vertical teeth g on their upper edges and ratchet-shaped teeth g' on their rearend portions. The front ends roo of the rakes are carried by the cranks b, and their rear ends are provided with upwardly Vmixed up with it. :return-bottom E' and is moved alongrit byV and rearwardly inclined bars G',fwhich slide the projections h', so that the Vsaid return bottom does not have to be shaken or placed at a steep angle. Y

The cleaningxdevices areA arrangedunderi the return-bottom E'. Y v Y I-I is the upper shoe,whioh receives. all th grain and other material from Vthe grain-bot tom dand the return-bottom'E'.

H' is the lower shoe, rwhich supportsV the grain plates or shelves. The rear end of the Y lower shoe isprovided with two similar slots t', whichv engage with pins fi', which project from the respective sides of the casing.

I is the upper cleaning-roll, and I' is the lower cleaning-roll-V Both of these rolls are journaled in the casing and are provided with grooves of anyapproved form. The upper shoe is provided with a comb J, arranged in front of the roll I, and the roll I is provided with ca'msj for'the sides of the upper shoe to rest on. The cams j are'preferably square. The rear end of the upper shoe is pivoted to Vthe lower shoe by pins j'. c

-K are similar slotted brackets secured to the upper shoe between the pivot-pinsj andl the upper roll I, and 7i; are pins which project from the lower shoe II' and normally rest on the bottoms of the slots in the brackets K, so that both shoes may be supported on the cams j and the pins t'. The cams j jog both shoes as, the upper roll I is revolved.

L is the first grain plate or shelf supported by the lower shoe H' under the upper roll I, and L' is the second grain-plate supported in the shoe Il' under the roll l'. These grainplates have Yledges 7a' on their front edges to prevent the grain from sliding off them too freely.

M is a toothed comb secured to the first grain-plate in front of the lower roll I', and M is a toothed comb secured to t-he second grain-plate L' and projecting over the apex of the divider-bar m.

The divider-bar m is stationary and is secured to the casing A, so that it is not affected by the movement of the lower shoe. This divider-bar is triangular in cross-section and has a plate m' secured to its substantially vertical front side and projecting below its bottom.

All three combs M', M, and J are adjustedsimultaneously with respect to the dividerbar and the two cleaning-rolls by moving the shoes H and II' longitudinally in the casing.

The shoes are moved by means of two similary rods N, provided with pins n at their rear ends, which engage with notches in the. lower shoe. The rear ends ofthe rods N are pivoted to similar levers n', carried by a shaft Y N', which extends crosswise ofthe machinequadrant O', secured to the casing.

The Vshaft N' -is preferably square or has a VsquareV end on which the lever O is loosely mounted. A pocket p is formed in the lever O, and p' is a spring which is inserted in the said pocket p and bears on the shaft N', so

that the catch o is forced'into engagement withione ofV the notches o'. VThe upper end of the lever forms a pointer P, and the casing is appropriately marked behind the pointer to indicate the positionfof the points of the combs. The lever is rocked on-its shaft against the pressure of the spring to withdraw thezcatch from the' notch before operating the lever to turn the shaft and adjust the positions ofthe combs. The ends of the notched casing.A A lever-O is mountedV on the Vshaft 1 N' outside the casing and is provided with a catch 0', which engages with Vnotches o' in aV quadrant are provided with stops P'fto prevent the lever @from being moved too far in eitherr direction. Y

Qis a shaft extending crosswise of the machine under the first grain-plate L, and q is arlever onthe end of the shaft Q outside the casing. The lever q is similarfto the lever O and it engages with a notched quadrant in a rrsimilarimanner. Two similar cams q' are secured on kthe shaft Q, and when these cams are raised they lift the rear end of the lower shoe, so that itis no 4longer'supported by the slotted brackets K. The lower shoe can be raised, so that no ljogging motion is imparted to it from the upper shoe by the cams j on the upper cleaning-roll, and this is very advantageous in cleaning some kinds and conditions of grain. More or less jogging motion can be given to the lower shoe by varying the position of the cams q' and permitting' only a part of the motion of the upper shoe to be communicated to the lower shoe.

R is the grain-spout, and S is the tailingsspout. Each of these spouts isprovided with a conveyer of approved construction, such as a spiral auger-shaped conveyer, for discharging its contents.

R' is the tailings-shoe. The front end of this shoe rests on a cross-bar fr, which forms a portion of the grain-spout, and its rear end is supported by pivoted links r'. These links have a rod s extending under the shoe R', and they are pivoted to pins projecting from the machine-casing.

A shaking motion is imparted to the shoe R' by means of two similar eccentrics s' and eccentric-rods t, which are connected to the rod s. The eccentrics s' are secured on the driving-shaft S' of the straw-stacker T, which is of any approved construction.

T is a serrated plate secured to the shoe R' under the divider-bar, and t' is a removable i oo IIO

chaffer-riddle dropped into the slice R behind the plate T and secured temporarily by any approved fastening device. The riddle t is of any approved construction, such as upwardly and rearwardly inclined slats having openings between them for the tailings to fall through. The riddle t can be taken out altogether or other riddles having different sizes of openings may be substituted for it according to the requirements of the material passing over it.

U is a serrated return-bottom or gatherboard secured in the shoe R and conducting everything that falls through the riddle t into the tailings-spout S.

U is a screen or sieve of approved construction and preferably formed of perforated zinc. This screen U is supported in the front part of the shoe R in an inclined position under the grain-plates L an d L'. A return-bottoni or gather-board at is connected bya hinge u atits rear end to the shoe R' and its front end rests on a cross-bar' U secured to the shoe.

V is a double-ended turn-button for holding the bottom 'a down on the cross-bar o, so that the screenings which slide down it can pass off its front end and fall down the screenings-spout V. Then the screen is not required in use, the bottom u is raised and the turn-button V is turned around so as to come above the cross-bar n and hold the bottom in its raised position.

IV is the chamber for afan or other similar device for supplying a blast of air to t-he cleaning devices.

iV is the blast-board, and w is the blastpassage.

The fan. is of any approved construction.

Rotary motion is imparted to the crankshaft, the two cleaning-rolls, and the strawstacker shaft in the directions of the curved arrows by any approved driving devices,such as belt-pulleys secured on the ends of the respective shafts and rolls. A belt or belts pass over these pulleys. These driving devices are not shown, as any approved driving devices can be used. The grain, chaff, or other material slides down the upper shoe and the grain forms piles on the grain -plates The good grain falls through the teeth of the combs and slides down the front faces of the piles of grain onto the screen IIy in the tailings-shoe. The blast blows out the lighter chaff and the heavy rubbish is carried over the tops of the grooved cleaning-rolls. The lighter grains which fall on the rear side of the pile of grain on the first grain-plate are treated over again at the second grain-plate, and any good grain which passes over the second grain-plate is removed by the comb over the divider-bar. The plate m on the dividerbar causes one part of the blast to pass upward through the teeth of the comb M and the other part to pass upward through the chaffer-riddle. The chatter-riddle removes all the heavy rubbish and Worksit rearwardly onto the straw-stacker. The screen U removes the very small seeds and grains of dirt from the good grain before letting the grain pass into the grain-spout, and the provision for closing this screen is made, because threshermen do not always consider it Worth While to remove the fine seeds from the grain. The straight arrows indicate the direction of the blast passing through the cleaning devices.
